For What It's Worth
The Challenge

This is a great project. One issue that causes concern is that the effect of the gearing makes the comparisons less useful than if gearing were fully taken into account. So, this thing could be upgraded more firmly out of the "entertainment" category if folks could be sure to always state what their final drive gear is (e.g., 4.86, 5.43, etc.) and also state what their 3rd gear is (e.g., 1.14 or 1.17, etc.) and also the tire manufacturer's actual stated (not calculated from the tire size) "revolutions per mile" rating for the tires being used. If somebody does not have the "revolutions per mile" official number rating from the manufacturer, then I suppose we could look that number up after getting the exact make and model and size of the tire. My guess is that after normalizing for gearing, the chart results could become extremely impactful. I'd also make a checkbox so people could indicate the estimated altitude at which the tests were done, and also a checkbox to indicate, a some did, a two-way run average (helps to control for hills).
